REPORT OF THE COMMISSIONER OF FISHERIES. 103 



thus kept informed of the current work of the service of which they 

 are a component part. Every employee receives a copy of each issue 

 and maintains a file. In the course ot the year it was necessary at 

 times to increase the number of pages to accommodate all the matter 

 desirable for publication, and the monthly edition has also been 

 enlarged. 



Effective February 1, 1917, the Bureau discontinued the free dis- 

 tribution of its general publications. This action was necessitated 

 by the increasing demands and the limited allotment available for 

 printing. _ Hereafter applications for publications will be referred to 

 the Superintendent of Documents, who will supply them at prices 

 representing the actual cost of paper and press work. Tlie only excep- 

 tions will be institutions and specialists collaborating or exchanging 

 with the Bureau and State and foreign fishery officials. Documents 

 issued in the Bureau's exploitation and propaganda work, together 

 with the Commissioner's amiual report, statistical bulletins, and the 

 Fisheries Service Bulletin, will be supplied as heretofore.
